Abstract :Purpose: This study was done to analyse the influence of fixed dental prosthesis insert ignore into journalissuearticles values(FDP); on brain function by analysing power spectral density of partially edentulous patients Materials and Methods: The study included unilateral missing mandibular molar replacement patients. The patients were restored with three-unit metal ceramic FDP restorations. The cognitive function was analysed with a mental state questionnaire. Power spectral density insert ignore into journalissuearticles values(PSD); analysis of EEG alpha waves was made pre- treatment, post treatment and 3 months after FDP treatment to analyse the brain function. The data in various phases were obtained before and after chewing. The results were statistically analysed. Results: The mean pre and post treatment PSD was 0.0175 insert ignore into journalissuearticles values(SD ±0.0132); and 0.0178 insert ignore into journalissuearticles values(SD ±0.0135);. The mean post treatment PSD after three months was 0.024 insert ignore into journalissuearticles values(SD± 0.019);. The results were analysed with repeated ANOVA and were statistically significant.insert ignore into journalissuearticles values( P < 0.01);. Conclusion: The study displayed improvement in brain function of partially edentulous patients with FDP rehabilitation
